Blizzard have now commented on the tailoring suspensions and reversals, explaining what exactly happened and saying there might be improvements to the UI coming in a future patch.

Tailoring (Source)

Earlier this week we fixed a bug that had allowed Tailors to circumvent a long cooldown in Tailoring, and quickly ascertained that some players had done so a great deal, so we actioned those players in accordance with how much the exploit was used. Earlier today, after further investigation, we came to understand that some of those we suspended likely didn’t have a deliberate intent to exploit and were simply doing something that appeared to be naturally available. As a result, we’ve now reversed most of these suspensions, so that only the most egregious cases remain penalized.

As a result of this, we’ve heard a lot of feedback about the crafting UI and tooltips therein, and we’re looking into improvements that we can make there in a future patch.

Thank you for your understanding.
